    Hello, I hope I'm posting this in the correct forum.

    I have been using an external hard drive nexstar 3 for a couple of years now. Trouble is, I've noticed that quite a number of files (notepad, word etc.) and also many image files are missing or corrupt. I have defragmented hard drive as well as searched for errors.

    It's not full to capacity, in fact it 125 GB of free space left, so I'm not quite sure what's going on. Is there anything I can do to get my files and images back? Images are there but when I attempt to open them the error in a pop up states:

    1. could not complete your request because invalid SOS, DHT, DQT, OR EOI JPEG marker is found before a JPEG SOI marker

    2. could not complete your request because an unknown or invalid JPEG marker type is found

    Word docs/notepad files are also there but again when I go to open them the documents are full of weird text.

    Not all files are corrupt, most I can view but I would say that at least 30% of the docs and images on the external HD are corrupt in some way. Can anyone suggest anything, or are they pretty much lost for good?

    Thanks

    p.s I'm not sure if I need to give more info on the hard drive??

    Welcome to the TSG forums...

    As you mentioned, more information about your external HDD would be appreciated... I'm curious about the HDD inside your external enclosure; how is it formatted? FAT32 or NTFS? What size is it? What make and model is the HDD itself? I realize that you might not have ever opened the enclosure, but I'd really like to know some specific details about the HDD... I understand that it is a Nexstar product, but I want to know the BRAND of the HDD itself to see if we can do some tests with disk utility software from the HDD maker...

    The BAD news is, those corrupted files are probably damaged beyond repair. I'd suggest that you copy them (COPY them, do NOT try to MOVE them) onto your internal HDD as soon as possible, then burn them to a CD/DVD, just in case any of them can be salvaged. I know that will seem like a lot of work; it IS a lot of work, but if you really want to try to save any of that data, burning those files to an optical disk is probably your best bet.

    OTOH, if you have some fairly large flash drives (AKA USB thumb drives) lying around, you could try to copy the files from the Nexstar3 HDD to the flash drives, which would avoid the process of copying to the internal HDD first, then burning them onto optical media...

    Lastly, just about ANY type of flash media you can read and write to from your computer would also work; my digital camera uses SD media, and I have SD card readers in two of my systems. I've used my SD cards to move files when all my thumb drives were full or in use...

    Best of luck to you; I hope this turns out well for you...
